Description: <b>Whole Body Vibration (WBV)</b> is a mechanical intervention in which individuals stand or exercise on a vibrating platform, producing oscillatory mechanical stimuli that activate neuromuscular, endocrine, and circulatory responses. In oncology contexts, WBV is not a direct cytotoxic therapy. Its relevance lies primarily in supportive care, including preservation of muscle mass, mitigation of cancer-related fatigue, improvement of bone density, enhancement of circulation, and modulation of inflammatory signaling. Preclinical mechanobiology research suggests mechanical stimuli can influence bone remodeling (RANKL/OPG axis), myokine release (e.g., IL-6 in exercise context), and possibly immune tone. However, WBV should be categorized as a supportive or rehabilitation modality rather than a tumor-targeting intervention. Clinical evidence in cancer patients primarily addresses quality of life, sarcopenia, and functional performance.<br>

<h3>AD Summary — Whole Body Vibration (WBV)</h3>
Whole Body Vibration (WBV) is a mechanical intervention that delivers low-amplitude, oscillatory stimuli through a vibrating platform, activating neuromuscular and neurovascular pathways. In Alzheimer’s disease (AD) research, WBV is explored as a non-pharmacologic intervention aimed at improving cerebral blood flow, reducing neuroinflammation, enhancing neurotrophic signaling (e.g., BDNF), and mitigating sarcopenia-related frailty that contributes to cognitive decline. Preclinical studies suggest WBV may reduce microglial activation, lower pro-inflammatory cytokines, and support hippocampal plasticity. Clinical data in AD populations are still limited but suggest potential benefits for balance, mobility, and possibly cognitive performance. WBV should be positioned as a supportive neurorehabilitative modality rather than a direct disease-modifying therapy.<br>
